Agreement in accordance with Section 8.  The period during
which CONSULTANT shall serve as a Consultant to the COMPANY
pursuant to this Agreement shall constitute the "Consulting
Period".

     2.   Duties.  CONSULTANT shall serve as a consultant to
the COMPANY in the activities of the COMPANY set forth in

disclose or deliver any proprietary or confidential
information of third parties in dealings with the COMPANY or
in providing the services under this agreement.  CONSULTANT
represents that he/she is not a party to any existing
agreement that would prevent him/her from entering into this
Agreement, and that the only agreements with third parties
which may restrict his/her consulting activities on behalf
of the COMPANY at the time of this Agreement are
CONSULTANT's obligations pursuant to the agreements set
forth in Schedule A.  The COMPANY understands and agrees
that during the Consulting Period CONSULTANT may be retained
by other companies, corporations, and/or commercial
enterprises which are not engaged in the design,
development, manufacture or marketing of products similar to
those of the COMPANY.  CONSULTANT agrees to inform the
COMPANY of any such agreement immediately.  CONSULTANT
agrees to use his/her best efforts to segregate work done
under this Agreement from all work done at, or for, any such
company, corporation, and/or other commercial enterprise.
In any dealings with any such company, corporation, and/or
other commercial enterprise, CONSULTANT shall protect and
guard the COMPANY's "Confidential Information" (as defined
in Section 5.1 below) in accordance with the terms of this
Agreement.

          3.2  Conflict of Interest.  CONSULTANT warrants

other than those referred to in Section 3.1.

     4.   Compensation.

          4.1  Consulting Fees.    The COMPANY agrees to pay

services under this Agreement consulting fees (the
"Consulting Fees") as set forth in Schedule A.  Payment of
the Consulting Fees will be made within 30 days after the
receipt of CONSULTANT's invoice.

          4.2  Employment Taxes and Benefits.  CONSULTANT
acknowledges and agrees that it shall be CONSULTANT'S sole
obligation to report as self-employment income all

services as a consultant.

          4.3  Legal Relationship.  CONSULTANT shall be an

no event be entitled to any fringe benefits payable to
employees of the COMPANY.

          4.4  Expenses.  CONSULTANT will be reimbursed only
reasonable costs and expenses incurred in performing duties

expenses was approved in advance by an authorized individual
of the COMPANY.  Such reimbursement shall be made within

documentation of such costs and expenses.

such as maintaining a competitive advantage or avoiding
undesirable publicity.  CONSULTANT will keep Confidential
Information secret and will not allow any unauthorized use
of the same whether or not any document containing it is
marked as confidential.  These restrictions, however, will

facilities of the COMPANY, its subsidiaries or affiliates,
or (ii) are made, conceived or completed by CONSULTANT
during hours in which CONSULTANT is performing services for
the COMPANY or any of its subsidiaries or affiliates.  It is
understood that nothing contained herein shall affect the

improvements and other innovations of any kind that
CONSULTANT may make, conceive, develop or reduce to
practice, alone or jointly with others, in the course of
performing work for the COMPANY or as a result of that work,

all related patents, patent applications, copyrights, mask
work rights, trademarks, trade secrets, rights of priority
and other proprietary rights.  At the COMPANY's request and
expense, during and after the period during which CONSULTANT

and cooperate with the COMPANY in all respects and will
execute documents, and subject to  reasonable availability,
give testimony and take further acts requested by the
COMPANY to acquire, transfer, maintain and enforce patent,
copyright, trademark, mask work, trade secret and other
legal protection for the Innovation(s).  CONSULTANT hereby
appoints the Secretary of the Company as CONSULTANT's
attorney-in-fact to execute documents on CONSULTANT's behalf
for this purpose.

               c)  Moral Rights Waiver.
               CONSULTANT hereby irrevocably transfers and
assigns to the COMPANY any and all "Moral Rights" (as
defined below) that CONSULTANT may have in or with respect
to any Innovation.  CONSULTANT also hereby forever waives
and agrees never to assert any and all "Moral Rights"
CONSULTANT may have in or with respect to any Innovation,
even after termination of CONSULTANT's work on behalf of the
COMPANY.  "Moral Rights" mean any rights of paternity or
integrity, any right to claim authorship of an Innovation,
to object to any distortion, mutilation or other
modification of, or other derogatory action in relation to,
any Innovation, whether or not  such would be prejudicial to
CONSULTANT's honor or reputation, and any similar right,
existing under judicial or statutory law of any country in
the world, or under any treaty, regardless of whether or not
such right is denominated or generally referred to as a
"moral right".

          6.3  Legal Proceedings.  Whenever requested to do
so by the COMPANY, CONSULTANT shall promptly deliver to the
COMPANY evidence for interference purposes or other legal
proceedings and testify in any interference or other legal
proceedings which relates to any matters on which CONSULTANT
has provided services to the COMPANY.
 
         6.4  Non-Infringement.  CONSULTANT represents and
warrants that the services performed under this Agreement
and the Innovations made or contributed by CONSULTANT
hereunder will not infringe on any rights of any third
party.

          6.5  License.  To the extent that the COMPANY's
use or exploitation of any Innovations made or contributed
by CONSULTANT hereunder may require a license from
CONSULTANT under any other proprietary rights held by
CONSULTANT, CONSULTANT hereby grants the COMPANY a fully-
paid, royalty-free, perpetual, worldwide license to make,
use, sell, copy, modify, distribute, perform, display and
otherwise exploit such Innovations.

     7.   Non-Solicitation.  CONSULTANT agrees that, during
the Consulting Period and for a period of two years after

Period, CONSULTANT will not solicit or recruit Cadence
employees for any other employers outside the COMPANY or
employ any of the employees of the COMPANY without its prior
written consent.

     8.   Termination.  The Consulting Period may be
terminated immediately, at-will by the COMPANY or CONSULTANT
for any or no reason upon notice to the other party.  The
covenants and agreements set forth in Sections 5, 6 and 7
shall survive the Consulting Period and remain in full force
and effect regardless of such termination.

this Agreement invalid or unenforceable as applied to any
circumstance, that provision shall be enforced to the
maximum extent permitted by law, and the other provisions
will remain in full force and effect.
